[摘要] 目的 探讨高分辨率CT对肺孤立性磨玻璃样病变的鉴别诊断价值。方法 回顾性分析华北石油管理局总医院心胸外科2015年1月—2016年1月经术后病理证实的60例肺孤立性磨玻璃样病变患者的临床资料,术前1月均行高分辨率CT及胸片检查,分析胸片及CT在肺内磨玻璃样病变中的诊断意义。结果 74个病灶中,肺腺癌共48个(64.86%),非典型性腺瘤样增生10个(13.52%),炎症性病变16个(21.62%)。高分辨CT对于肺内磨玻璃样病变诊断率明显高于胸片(96.50%>51.40%,χ2=11.14,P<0.05)。结论 高分辨率CT对肺孤立性磨玻璃样病变具有显著的诊断价值,能够在术前对良、恶性病变进行有效鉴别。

[Abstract] Objective To study the value of high resolution CT in differential diagnosis of pulmonary solitary ground-glass opacity. Methods 60 cases of patients with pulmonary solitary ground-glass opacity confirmed by the postoperative pathology from January 2015 to January 2016 were selected and underwent the high resolution CT and chest film examination in 1 month before surgery, and the significance of high resolution CT in differential diagnosis of pulmonary solitary ground-glass opacity was analyzed. Results Of 74 focuses, there were 48 cases with adenocarcinoma of lung (64.86%), 10 cases with atypical adenomatous hyperplasia (13.52%) and 16 cases with inflammatory lesions (21.62%), and the diagnosis rate of high resolution CT in pulmonary solitary ground-glass opacity was obviously higher than that of chest film(96.50%>51.40%,χ2=11.14,P<0.05). Conclusion The value of high resolution CT in differential diagnosis of pulmonary solitary ground-glass opacity is obvious, which can effectively identify the benign and malignant lesions before surgery.

隨着CT技术的不断完善和发展,有效提高了肺内磨玻璃病变的诊断准确率,尤其是高分辨率CT在肺孤立性磨玻璃样病变检测中的应用效果显著。多项研究认为,肺内局灶性磨玻璃结节与肺腺癌密切相关。胸片在肺内小病变中诊断价值较低,在高分辨率CT图像下,肺孤立性磨玻璃结节表现为密度轻微增加,还能看到内部支气管的血管纹理,这种影像学表现的原因很多,例如炎症性病变、局限性纤维化、出血等[1]。肺孤立性磨玻璃样病变与肺癌、局灶性纤维化、炎症等疾病的临床鉴别诊断存在一定的困难。该研究回顾性分析了2015年1月—2016年1月经术后病理证实的60例肺孤立性磨玻璃样病变患者的临床资料,给予其高分辨率CT及胸片检查,现报道如下。
